In my case, as long as TI-BASIC is as fast then I'm fine, although some of my games would be hard to port because the calc has 3 KB less RAM. I'm thinking of example about Illusiat 12, which had ERR:MEMORY happening often in certain chapters if you had 2 save files, and Illusiat 8.

Also I hope that the LCD driver isn't too slow, otherwise there will be an huge impact in ASM. However, some people on IRC suggested before that this calc might actually be a low-end TI-Nspire in disguise and that the Z80 ASM compatibility might be just an emulator or something.

That said, with this calc coming out, we now know why the TI-Nspire CX lacks interchangeable keypads and TI-84 Plus emulation.

Indeed, although from what I remember, TI was working on the CX for at least 1 year before it was finally leaked. They could have been working on the 84 Plus C Silver Edition for over a year before it was leaked as well.

I would like to assume that there is a way to disable to top bar.

Did the z80 calculators have a clock before?

the 84+/SE did, and i think the 83+SE did as well.

Nope. The 83+SE doesn't.

The TI-83+SE is the beta edition of the TI-84+ series. Hardware-wise, the TI-83+SE is a major change compared to the original TI-83+, for it switches to a very different, ASIC-centric design; the TI-84+(SE)'s only major change is the addition of the USB port. (The three crystal timers all use the same single quartz crystal as the primary clock source; the TI-84+(SE) real-time clock uses the same crystal, too, so adding an RTC is a simple matter of adding a 32-bit seconds counter and a 15-bit subcounter.)
